Hi, Rather than addressing the issue of how many column family may be used and query performance on them, I would like to address the problem of hierarchical data.
We were facing an issue of storing hierarchical data in one of our applications and for solving that, and many other features, we turned developed Smart CMS - smart-cms.org If it sounds interesting to your problem let me know, we can then collaborate in more details.

It is feasible to have 2 or 3 sub column families within a single column family???I want to store xml data in Hbase and I have sub tags that may go down to 2 or 3 levels. Regards, Mohammad Tariq
